lMPRVENIENIa iN LOM-SHUTTLES.

Specification forming part of Letters Patent No. 124,967, dated March 26, 1872.

Vthe take-up brings into action, at times, a

small number of the warps, and which is constantly varying, as the gure of the fabric tobe woven varies, by the action of the Jacquard mechanism and the take-up 5 and my invention consists in the construction, arrangement, and operation of pulleys, by which the above object is secured. The iilling-thread is conducted to the warps from the` periphery of a pulley or wheel suitably placed upon the shuttle-plate, instead of passing directly from the bobbin. This wheel being revolved in one di-` rection, by the tension of the lling-thread at the weaving-point, the thread is wound several times about the periphery of the wheel before it is conducted to the warps, and is unwound from this pulley by the movement of the shuttle. Another wheel, acted upon by a reacting spring at its axis, is connected with the irst-mentioned pulley by a cord passing around the periphery of the reacting pulley, so that both pulleys are reversed and the thread taken up whenever a slack occurs.

In the accompanying drawing the shuttle is represented in front elevation; and in Fig. l2 in a top view from the bottom downward-ct being the shuttle-plate; b, the bobbin; c, the thread or weft-yarn 5 e, the pulley or wheel fixed to the shuttle-plate, around which the thread is passed several times before passing to the war-ps; f, the reacting pulley. g is the spiral reacting spring, by which the reverse motion is produced; and the (Fig. 2) line h represents the cord which connects the two wheels or pulleys.

The construction of my improvement is as follows: Upon the face of the shuttleplate a the pulley e is placed, and which has affixed to it a metallic disk, e1, having a hub or bush at its center, e2, which turns upon a short axis fixed on the shuttle-plate, thus affording theI wheel e the required bearing. The central portion of the outer face of the pulley c is made hollow or depressed, and the pulley has no axis or bearing on this side, so as to leave an unobstructed space or chamber for the free movement of the thread both in the forward and-reverse movement of the pulley. A smaller pulley,f, is secured to the shuttle-plate by its axis, upon which it revolves. A fine spiral spring, g, is attached to the hub of the wheel f, and to a bearing fixed on the transverse narrow plate t'. A ne cord, fast at one end to the metallic disk of the pulley c, is wound around the hub 6 2 several times, and around the grooved periphery of pulley fseveral times, and its end fastened therein in ysuch manner that, when the illing-thread is drawn out over pulley e, as hereinafter described, it will wind up the spiral spring g by the rotation of pulley f, and thereby cause the spring to act upon the pulley j' in a reverse direction when it is relieved from the tension of the thread. The illing-thread c is conducted from the bobbin by rst passing inward through a hushed opening, k, in the transverse strap or plate, z', which opening must have its center coincide exactly with the center of the pulley e. From this opening the thread is passed through a hushed opening in the rim of the pulley to its grooved periphery, and is then wound from right to left several times, according to the amount of slack required to be taken up at any time, and then is passed out through a bushed opening in the curved side ofthe shuttle-plate at Z, on

a line with the grooved periphery, from whence it passes to the warps.

When the shuttle is operated, the end of the filling-thread being fast to the warp-thread, the movement of the shuttle causes the thread to unwind upon the pulley e until it runs direct from the bobbin'through the holes above described. llhis unwindin g causes the pulley to rotate from right to left, and, by the connecting-cord h, causes the pulley j' to rotate and thus wind up the spiral spring g. As soon as the tension upon the iilling thread slackens, so as to leave a slack in the thread from a diminished number of warps being in action, the reaction of the spiral spring reverses the first motion of pulley f, causing the therein as my invention, and for which I desire to secure Letters Patent, is-

1. In combination Awith a loom-shuttle, the pulleys e' and f, the reacting spiral spring g, and connecting-cord h, arranged, constructed, and operating as and for the purpose set forth.

2. In combination with the bobbin b, the pulley e, constructed and operating as and for the purpose set forth.
